"See you later, alligator!"
Translation:Hẹn gặp lại, cá sấu!
Mmm well alligators have wider, U-shaped snouts, while crocodile front ends are more pointed and V-shaped. And when their snouts are shut, crocodiles look like they're flashing a toothy grin, as the fourth tooth on each side of the lower jaw sticks up over the upper lip. For alligators, the upper jaw is wider than the lower one, so when they close their mouths, all their teeth are hidden.
